Corona Discharge Station FA-52 Series

basic information
Product description

Corona Application

Corona treatment is known as dielectric barrier discharge. It is mainly used for surface treatment of plastic film or plastic sheet. Before ink printing, laminating, blowing, coating, gluing, material modification, polymerization, film metallization, casting and adhesions of the materials, in order to make the surface have stronger adhesion (i.e. higher dyne level), and prevent the printing and gluing from fading, dropping and other poor effects, it is necessary to use corona surface treatment.


Corona Application

Corona is to use high-frequency and high voltage to generate corona between the discharge electorde and the corona roller to form a low-temerature plasma area. Through the air ioniztion between the two medium, ozone is produced. It is on oxidant, which can immediatey change the molecular structure of the plastic surface and make it from non-polar to polar. At the same time, the corona will make the surface of the material have small and uneven holes to rough the surface and enhance the surface activity, after the surface tension is increased, so the ink, glue, etc. can deeply penatrate into the material because of the treatment so it acieves the desired printing and gluing effects.
